    As an online chemical trading market, we are supposed to offer helpful information about Urea suppliers that could help urea traders to find trustful suppliers. So here we introduce some of the best Urea suppliers: and some other tips that could help you to buy and sell Urea safer.

    First notice that Urea is also called carbamide. It is rich in nitrogen, so it is a good choice for producing livestock supplements. It is soluble in water and does not cause any harm.

    Top 10 Urea Suppliers in Iran

    The trend of industrial urea production in the world is significant. Widely used in the production of animal feed additives, the pharmaceutical industry, medical and laboratory industries, etc. It has led to increased demand for purchase. For this reason, in this section, we introduce the most important urea production plants in Iran and the Middle East.

    Urea Buying Guide

    It is important for most customers to buy industrial chemicals that provide quality products at competitive prices. This is also true of carbamide purchases. In this section, we will be familiar with the purchase guide and physical and chemical characteristics.

    Product Quality

    This compound is sold in the form of a white solid color. When shopping, make sure the bags are completely sealed. Any color change in this material can indicate that it is inferior. Carbamide is high quality, white and free of any bad smell.

    Physical and chemical properties of urea

    The chemical formula of carbamide is CH4N2O. It is solid and white and odorless. It is soluble in compounds such as ethanol, acetonitrile, glycerol in certain amounts. The most important compound similar to this material is called thiourea.

    Physical and chemical properties
    Chemical Formula CH4N2O
    Molar mass 60.056 g·mol−1
    Appearance White Solid
     Density 1.32 g/cm3
    Melting point 133 to 135 °C 
    (271 to 275 °F; 406 to 408 K)
    Solubility 500 g/L Glycerol
    50g/L Ethanol
    ~4 g/L Acetonitrile
    Acid dissociation constant 13.9

    Urea Manufacturing Methods

    1-Industrial production of CH4N2O

    In factories, carbamide is a product made from ammonia and carbon dioxide. In the vicinity of ammonia plants, an industrial carbamide manufacturing plant is also expected to be operating. 

    2- Synthetic production of carbamide

    This synthetic method was first invented in 1922. This compound is formed in several processes of reactions. These reactions are below.

    2 NH3 + CO2 ⇌ H2N-COONH4 
    ΔH = -117kJ / mol (at 110 atmospheres and 160 degrees Celsius) 
    H2N-COONH4 ⇌ (NH2) 2CO + H2O
    ΔH = +15.5 kJ / mol (at 160-180 degrees Celsius)

    3-Laboratory production method

    These reactions are below.

    COCl2 +4 RNH2 → (RNH) 2CO +2 RNH3Cl
    NH4OCN → (NH2) 2CO

    Urea usages

    Industry name Usage
    Agriculture Production of chemical fertilizers containing nitrogen
    Paint and Resin Production of formaldehyde resin - production of melamine - production of plywood
    Automobile industry Application in selective catalysts to reduce vehicle exhaust pollutants
    Laboratory Preparation of protein-based solvents for research studies
    Cosmetic and beauty Production of skin care products - as a standard for measuring the amount of nitrogen in the blood - additive in the production of creams, shampoos and hair conditioners
    Animal feed Additive to animal feed (rich in nitrogen)
    Other uses of urea Production of teeth whitening products - an additive in the color bath - use as an additive in a fire extinguisher - as antifreeze

    Urea packaging and storage

    Urea is offered in 50kg and 1000kg bags. Transportation of bags should be safely.

    Maintenance, Loading and Delivery

    Loading and maintenance of carbamide is carried out according to standard procedures. This material should be stored in dry and cool warehouses, with full ventilation and away from incompatible materials (oxidizing compounds, chlorinated materials). 

    Urea Safety Tips

    Dust from this substance can irritate it by entering the respiratory system. Swallowing this substance causes nausea or digestive problems. Carbamide is chemically stable. It is better for people who are dealing with this material to wear safety work clothes, masks, glasses and gloves.

    Competitive price to buy urea

    Carbamide is used for chemical fertilizer production and then for animal feed. This material is offered in various quantity for consumer industries. You can buy high quality carbamide directly from suppliers through the Shimico website.

    who invented urea?

    urea is an organic compound that is the main nitrogen-containing substance in the urine of mammals. The French chemist Hilaire-Marin Rouelle isolated it from urine for the first time in 1773. It was first synthesized from inorganic materials in 1828 by the German chemist Friedrich Wöhler, which was a landmark achievement in chemistry. Wöhler was able to produce carbamide through two combinations of silver cyanate and ammonium chloride. The chemical formula of this compound is shown as CO(NH2)2.
